ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed January 15, 1913. Serial No. 742,159.

To all 10h out it may concern Be it known that I, GI-mmins H. Lose, a citizen of the United States, and a resident of Fail-bury, in the county of J efi'erson and State of Nebraska, have invented certain new and useful Improvements in Acetylene Gas Generators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in acetylene gas generators, of that type placed under ground; and the object of my invention is to provide a generator of this general character, of a simple and inexpensive nature and of a compact and durable construction, including a relatively stationary chamber the bottom forming a sludge chamber, and having a superposed carbid holder, with means to automati-ally ope ate a valve, insuring a proper amount of carbid feeding into the generating chamber at the proper instant.

My generator, further, provides a readily operated means for emptying the sludge chamber, the construction being such that the gas bell will provide an even pressure at all times.

With these and other objects in view, my present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

Figure 1 of the drawing shows a vertical section of an acetylene gas generator constructed according to my invention, with portions broken away. Fig. 2 shows a horizontal section taken at the bottom of the generating tank.

In carrying out the object of my invention, I provide a tank 1, including the bot tom 2 and lid 3. At suitable points are secured the vertically disposed guide rods 4,

l, while secured a suitable distance above the bottom 2, is the supporting flange 5. Extending from this flange .5 are the brace bars 6, which at their outer ends are secured to the pan 7, which pan has secured to it the supporting legs 8 resting upon the bot tom 2. As shown this pan has an ear 9 carrying the pin 10, which gives pivotal support to the lever 11, having the enlarged ends 12 and 13. Hold within the tank and arranged at times to rest upon the flange 5 is the gas bell 14, the breast 15 of which is provided with the guide rollers 1 arranged to roll and guide upon the rods l. The breast 15 has the nipple 2 and is provided with the outer collar 3 which extends into the bell a suitable distance and is provided with the bottom 5, from which extends the inner collar t, these collars 3 and 1 extending in parallel spaced relation. Secured to the outer collar 3 are the screws (3 'arrying the wing nuts 7. Arranged to be rcinovably he] d between the collars 3 and 1-, is the seal 8 in the form of a tubular member having the top 5). This top 9 is provided with two openings to receive the screw (3, so that by means of the wing nuts 7 the seal is held between the collars, this cmistruction being employed to form a water seal, as a suitable amount of water is placed within the annular housing formed by the collars and connected bottom. The top 9 is provided with the handle 16. Extending from the outer collar 3 are the braces 17, which at their lower ends are secured to a collar 18. Resting normally within the pan 7 with its upper end extending into the inner collar at and passing through the collar 18, is a member 19, forming a generating chamher. This member is of sheet metal and provided with the escape openings :1; and the perforations The chamber 1S) is provided with the bottom 20 having a suitable opening 20, and slidably held upon this bottom, is the valve plate 21,, having an extending pin 22, working through a slot within the bottom 20, so that the plate 21. can be shiftcd to expose the opening 20, within the bottom 20. llxtending centrally from the bottom 20 is a tube 23, which at its upper end is held within a cap 26, this cap in turn being held within a collar 2% having the arms 25, by means of which the collar is secured in position. 'llhese arms are suitably fastened at their ends to the generating chamber. Slidably held within the tube 23, and

passing through an aperture within the bottom 20, is the valve stem 30, which at its upper end passes through an opening within the cap 26. This stem at its upper end is provided with the valve 28 having the conical end 29, and seci'lred to the stem below this conical end, is the deflector 27. Secured within the upper end of the chamber 19,

is the dished bottom 32, which has a suitable opening, arranged for coaction with the conical end 29 of the valve 28. The opening within the bottom 28, is skirted by a circumscribing flange 30. Secured to the dished bottom 32, is the hood 31, in which the valve 28 reciprocates. The chamber A above the bottom 32 forms the carbid holder, this chamber being closed by means of a screw cap 33. Secured parallel to the generating chamber is the tube 35 which passes through thenipple 2 and at its lower end is secured by means of the bracket 34. This tube is closed by means of the screw cap 37, the tube extending a suitable distance beyond the breast of the bell 14E. Slidably held within this tube 34, is the valve rod 36, which extends a suitable distance below the gas bell, its lower end arranged to normally contact with the lever end 12. As shown the valve stem 30, is normally in contact with the lever end 13, the lever 11, balancing these two members 30 and 36. Secured within the tank and extending upward into the gas bell is the escape pipe 38 to which is secured a filter 39 having a screened opening 42 protected. by a shield 40. This shield extends outward and v.is intended to protect the gauze covering the opening 42. This escape pipe 38 is connected to the service pipe 41. y

The tank is filled with a suitable amount ofwater, while a suitable amount of carbid is placed within the ample carbid chamber. The parts being properly arranged the gas bell will restv upon the flange 5. The valve 28 will then be within the hood 31, for the reason that the valve rod 36 will be forced downward, by means of the cap 37 to tilt the opposite end 13 of the lever forcing the stem 30 upward to open the carbid valve. As the carbid drops into the generating chamber it encounters the water, with the result that the gas is generated. As the gas generates it escapes through the open ings 00 and fills the bell. As the gas accumulates the bell will gradually rise, and as the cap 37 recedes from the ends of the rod 36, the valve 28 and its connected stem 30 descends, resulting in the carbid escape opening gradually being closed by means of the conical end 29,'until, finally the valve is entirely closed. As the gas is withdrawn ting the emptying of the sludge from the chamber, forms an important feature of my invention. The chamber having been recharged and cleaned, can be reinserted with ease, accuracy, and despatch, insuring a proper operation of the working parts.

aving thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:

The combination in a device of the charac ter described, of a tank having a supporting flange near its lower end, of a pan secured near the bottom of said tank, a lever pivotally secured to said pan, a gas bell ar ranged at times to rest upon said supporting flange, a vertically disposed tube closed at its upper end and carried by said gas bell, a valve rod loosely held within said tube and contacting with the upper end thereof and arranged to normally rest upon one end. of

said lever, a closed generating chamber removably held upon said pan and extending I into said gas bell and having suitable escape openings, a tube, vertically disposed, with in said generating chamber, a valve stem heldwithin said last mentioned tube and extending beyond the ends thereof and passing through the bottom of said pan and resting upon the other end of said lever, a partition near the upper end of said chamher having a valve opening, and a valve secured to said stem arranged at times to close said valve opening, as and in the manner set forth. 7 7 V In testimony whereof I affix my signature,

in the presence of two witnesses.
